Trunnion Mounted Ball Valve
The Flow Control Group supply a complete range of Trunnion Mounted Ball Valves for a wide range of applications in the water, wastewater, oil and gas and industrial process sectors.
The specification and selection of a valve and its operating protocols is essential to the optimum performance of any valve. The Flow Control team have the knowledge and expertise to identify the correct valve for the desired application.
Trunnion mounted ball valves provide tight shut-off in larger, critical, high-pressure operations and specialized low-pressure applications. The seats of the valve are always in contact with the ball making for tighter seals that prevent leakages.
Trunnion mounted ball valves are extremely versatile. They are used in many different kinds of industries because of their customizable features. For example, SIO Trunnion Mounted Ball Valve features O-rings and fire-safe stem packaging that prevent leakages. It also comes with stainless steel sealant injection fittings for emergency stem or seat sealing. Trunnion mounted ball valves are used widely in chemical, petrochemical, oil and gas, LNG, hydrocarbon industries.
They are also used for many different kinds of applications including skids like turbine, compressor, generator, and separator, field gas, polymer, LNG, crude oil, and industrial gas processing plants, tank farms, automated process applications, hydrocarbon processing, and oil refinery feedstock lines. Trunnion mounted ball valves are suitable for both large scale high-pressure applications and compact, low-temperature situations.
Trunnion mounted ball valves are quarter-turn valves used to stop the flow of medium in pipelines. These valves feature a round or spherical disk in the center that rotates to start or stop the flow. This disk is called a ball and it features a hollow center. Ball valves are extremely versatile and are commonly used in industrial applications where tight shut-off is required.
Trunnion mounted ball valves feature additional support for the ball. This support is in the shape of a shaft and is called a trunnion. The trunnion absorbs any added pressure from the flow, reducing stress on the ball and seats of the valve. Trunnion mounted ball valves are used in high-pressure, large scale applications where low operating torque is required.
Additional information
| Types of Trunnion Mounted Ball Valves | Trunnion mounted ball valves are available in many different configurations. They are highly customizable so you can choose the size, type, and actuator that suits your needs. |
|---|---|
| Based on Body Configuration | Body configuration determines how a valve can be accessed for maintenance or repair. There are two types of trunnion mounted ball valves based on body configuration. |
| Valve Bore | The bore of the valve is the hole that is found in the middle of the disk or ball. Trunnion mounted ball valves have two types based on bore size. |
| Valve Assembly | The body of the valve may have one, two, or three pieces connected together though welded joints. There are two types of trunnion mounted ball valves based on the number of pieces. |
